Powder is not like paint, it will mirror the substrate when applied as a single stage.Single stage powder is 3-4 mils ideal. Multi stage, a color and a clear 2 coats will be 6-7 and 3 stage like some translucents require will be 10 and over. Powder does not like to be thick, the thicker it is the less chip resistance there is. There is a window to be adhered to. A solid color like a tgic black will show the machined rings in a centerline, and blasting to get a "tooth" will do little to remove the rings. The flats need to be sanded and the rings wiped with sandpaper to remove the highs, and then a light blasting to finish. Trouble is everybody and their cousin has bought an old oven and a powder gun and has really skrewed up the industry. They load powder on up prepped wheels and when the tire guy mounts tires the powder chips off. They have no idea on cure time and the powder is either under cured or over cured, which both will cause it to chip. And they load up the powder because of a re shoot or some other screw up and it chips too. Sand the centers with a D/A with 220, hand sand the radius the same to remove the rings, and tell them to keep the radius around the lugs/hub side somewhat thin, so the washers dont chip the coating and you should be good. And you probably will have to reseal the already old silicone sealing the halves from the 340-400 degree cure temp.

My Weld 2.0 rear centers were powder coated same color as the chassis. The coating was coming off at the lugs. I rattle can repainted them at least once. I was gonna get them recoated and spent forever trying to get all the coating off. Was quoted a pretty high price (I thought) to do em. I sold them after glass beading them at least 3-4 times. Bought polished centers.
From what I’ve seen, I’d pass on getting wheels done and get them polished. Do some work yourself as was described to sand out the machine grooves. They will polish up real nice if a pro does them with the right equipment. Finding someone is maybe the harder part. A chrome shop would have the equipment usually.
